Costco Sues US for Tariff Refunds

Costco has sued the United States government to ensure it receives refunds if the United States — Supreme Court of the United States rejects Donald Trump's authority to impose tariffs under the International Emergency Economic Powers Act. The lawsuit, filed in the U.S. Court of International Trade, highlights uncertainty over businesses' ability to recoup tariffs. United States — United States Customs and Border Protection denied Costco's request for more time to finalize tariff calculations, which Costco argues jeopardizes its right to full refunds. Dozens of other companies, including Bumble Bee Foods, EssilorLuxottica, Kawasaki Heavy Industries — Kawasaki Motors, Revlon, and The Yokohama Rubber Company, have also filed similar lawsuits. The United States — Supreme Court of the United States is reviewing the case on an accelerated basis, with a ruling pending. Costco has already taken steps to mitigate tariff impacts by reducing suppliers, increasing local sourcing, and relying more on its Kirkland brand.
